1、大六角高強(qiáng)螺栓完全可以替代扭剪型，反過(guò)來(lái)扭剪螺栓不能完全代替大六角。
1. The large hexagon high strength bolt can completely replace the torsional shear type, on the contrary, the torsional shear bolt can not completely replace the large hexagon.
2、螺栓：機(jī)械零件，配用螺母的圓柱形帶螺紋的緊固件。由頭部和螺桿（帶有外螺紋的圓柱體）兩部分組成的一類緊固件，需與螺母配合，用于緊固連接兩個(gè)帶有通孔的零件。 這種連接形式稱螺栓連接。如把螺母從螺栓上旋下，又可以使這兩個(gè)零件分開，故螺栓連接是屬于可拆卸連接。
2. Bolt: mechanical part, cylindrical threaded fastener with nut. A kind of fastener composed of head and screw (cylinder with external thread), which is used to connect two parts with through-hole by matching with nut. This type of connection is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
